Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in providing consistent and high-quality cellular coverage for vehicles due to changing Radio Frequency (RF) conditions and penetration losses, leading to Quality-of-Service (QoS) degradation across national borders where different frequency resources are regulated.
Innovation Solution
A mobile relay transceiver apparatus that determines and adapts radio resources based on the location of the vehicle, using a determination module to select appropriate access radio resources for communication with mobile transceivers and relay resources for communication with base stations, ensuring service continuity across geographical areas by switching between frequency resources as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile relay transceiver uses fixed frequency resources for relay link and access link, then device complexity is reduced, but service continuity is degraded when crossing national borders with different frequency regulations
Solution Approach 1:
The patent implements dynamic frequency resource selection where the mobile relay transceiver automatically adjusts the frequency resources used for relay link and access link based on location information and applicable frequency regulations. The system transitions from static to dynamic resource allocation, selecting different frequency combinations when crossing national borders to maintain service continuity while complying with local regulations.
Solution Approach 2:
The system employs feedback mechanisms by continuously monitoring location information and determining the applicable frequency regulation regime, then adjusting frequency resources accordingly. This closed-loop control ensures the transceiver maintains compliant and continuous service across different geographical areas with varying regulatory requirements.
2Adaptability or versatility
If the mobile relay transceiver dynamically adjusts frequency resources based on location, then service continuity across borders is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-configuring multiple frequency resource combinations for relay link and access link before actual deployment. When the transceiver enters a new geographical area, it quickly selects from pre-defined compliant frequency combinations based on location information, reducing the complexity of real-time frequency synthesis while maintaining adaptability to different regulations.
Solution Approach 2:
The patent changes the parameter of frequency resource allocation from fixed to variable based on geographical location and applicable regulations. By implementing location-aware frequency selection, the system adapts to different national frequency regulations, allowing the same hardware to operate compliantly across multiple jurisdictions with varying spectral requirements.
3Productivity
If the relay node uses the same frequency resources for both relay link and access link, then spectrum efficiency is improved, but interference between links increases
Solution Approach 1:
The patent segments the frequency spectrum into separate resources for relay link and access link operations. By allocating distinct frequency resources to each link type, the system eliminates mutual interference between relay and access communications, ensuring clean spectral separation while maintaining overall spectrum efficiency through coordinated resource management.
Solution Approach 2:
The system applies local quality by assigning different frequency characteristics to different functional links. The relay link uses specific frequency resources optimized for backhaul communication, while the access link uses separate frequency resources optimized for vehicle-to-terminal communication. This localized frequency optimization reduces interference while maintaining high spectral efficiency for each specific communication function.
